ERIK A. PEARSON, F PORTLAND, QREGON KEEPING MILK AND SIMILAR SUBSTANCESOB, LIQUIDS COOL WHILE IN TRANSIT Application filed. December 5, 1927.Serial No. 237,920.

This invention relates to an arrangement for keeping milk and similarsubstances, or

liquids such as milk, cool in milk bottles or similar containers -Whilein transit from milk depots or creameries to consumers and until pickedup by them for use.

The object of the invention is to provide the opening or mouth of thebottle or container with a receptacle made of a thin suitable materialsuch as cardboard or paranine paper, the receptacle to have a lateralflange at the top,resting on the ledge in the mouth of the bottle and ofa size to fit tightly within the flange or rim thereof and thus form aseal. After the milk in the bottle has cooled to ordinary temperature,the solid carbon dioxide is placed in the receptacle and a paper lineror cover in the form of a cup is placed over it. A paper closure disk isplaced on top of the lateral flange of the receptacle and is also fittedsnugly within the flange or rim of the mouth. As the ice melts thepasses out from under the edge of lining and up along the sides of thereceptacle and out 5 through a small hole or vent in the closure disk.

WVith the above and such other objects in View as may hereinafter morefully appear, I

have invented the device shown in the accompanying drawings, in whichFigure 1 is a vertical section of bottle or container showing icereceptacle with closure disk. I

Figure 2 is a plan view of ice receptacle.

Figure 3 is a vertical section of ice receptacle.

. Figure 4 is an enlarged part of view shown in Figure 1, showing icereceptacle. closure disk and lining.

Like reference characters indicate like parts through out the followingspecification and in the several views in the drawings in which 1indicates a milk bottle of the ordinary type, 2 is a receptacle of whichthe lateral flange 3 is resting on ledge 4 of the mouth of the bottle.The edge 5 of flange 3 is turned up slightly so that when closure disk 6is placed on top of it, they will be pressed together and form a tightjoint. 7 is a small hole or vent in closure disk 6 for the escape of thegas as the ice melts. 8 is a paperlining for the purpose of using thegas from the melting ice as a means for cooling the sides of thereceptacle.

While I have shown the receptacle to be cup like receptacle having alateral flange at the top of a size to fit within said flange or rim ofthe bottle and to rest on said ledge and a paper closure disk of a sizeto fit snugly within said flange or rim of the bottle so as to act as aclosure for both the bottle and re ceptacle.

2. In combination an ordinary glass milk bottle having in the mouththereof a ledge surrounded by an'upstanding flange or rim, a cup likereceptacle having a lateral flange at the top of a size to fit withinsaid flange or rim of the bottle and to rest on said ledge, saidreceptacle to have a cup like shaped lining resting on the bottom of thereceptacle.

3. In combination an ordinary glass milk bottle having in the mouththereof a ledge surrounded by an upstanding flange or rim, a cup likereceptacle having a lateral flange at top of a size to fit within saidflange or rim of the bottle and to rest on said ledge and a paperclosure disk of a size to fit snugly within said flange or rim of thebottle, so as to act as a closure for both the bottle and receptacle,said paper closure disk to have a hole in about the center thereof as avent for the escape of the gas.
